PRO STP

PRO STP is a speaker tester specially developed by UNiKA for sound engineers. Sound engineer can use PRO STP to transmit instantaneous 5VDC and constant pink noise through NL4 and NL8 to test the speaker impedance and wheater speaker be damaged or not.

Key Features

• Generate and output pink noise from XLR to mixeror self-powered speaker cabinet.
• Generate and output pink noise from NL4 and NL8 to speaker cabinet.
• Pink Noise is equipped with a dedicated on-off volume potentiometer.
• The momentary button to create 5VDC is used to detect the impedance of the speaker.
• 4 toggle switches are used to determine the 5VDC output to NL4 and NL8 wiring pins.
• The 4/8/16 ohms LED indicators are used to display the impedance result of the test.
